Application June so, 1947, Serial No. 758,061

Our invention refers to securing means for can tops or covers. v

The object of our invention is to provide a pair ,of spring controlledlatches for firmly seating and tightening the slip cover of any standardcan, whereby the same is held to its seat against blasts of wind, or inthe event the can inadvertently is knocked over.

It is understood that the set of latches may be readily attached to anystandard cans in use, or the same may be attached as a part of theequipment in the manufacture of new cans.

The device thus overcomes unsanitary conditions due to spilling orscattering garbage from an open can, and cans so equipped arepractically sealed to prevent the entrance of flies or other insectsthat would quickly develop germs or the like, or cause odors from thegarbage so stored.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of parts, substantially as hereinafterdescribed, and more particularly defined by the appended claim, it beingunderstood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of thephysical embodiment of the present invention constructed according tothe best mode so far devised for the practical application of theprinciples thereof.

In the drawings:

Figure 1 represents a side elevation view of an ash can having coversecuring means embodying the features of our invention.

Figure 2 is a fragmentary enlarged sectional view of one corner of thecan and top, illustratin the latch connection, the section beingindicated by the line 2-2 of Figure 3.

Figure 3 is a plan view of the same.

Figure 4 is a front elevation of the latch mechanism, in conjunctionwith fragments of the can and top.

Figure 5 is a sectional plan view through the can, illustrating certainof the latch details, the section being indicated by line 5-5 of Figure2.

Figure 6 is a detailed plan view of an offset arrangement between thebracket and ear.

Referring by characters to the drawings, A indicates an ash can, and Bthe slip cover thereof, it being understood that any type of can andcover may be employed in connection with our latch mechanism.

A pair of ears 2 are secured to the periphery 1 Claim. (01. 220-55) ofthe can top B by pointed sheet metal screws ,2. These screws are used tofacilitate the assemblage of the latch mechanism upon ash cans now inuse, and said screws due to their pointed ends, can readily be fastenedwithout the aid of drilling or the like, but can be punctured.

The outer ends of the ears project beyond the edges peripheral of theslip cover, and they are provided with end apertures 2".

Directly below the mouth of the ash can we similarly attach, by metalscrew, an angle iron bracket 3, having ofiset arms 3 apertured at theirends, the said arms and ears being in parallel relations.

Reciprocally mounted in the arm apertures, are rods 4 having at theirupper ends hook extensions 4', which extensions terminatewith dependingnoses 4" adapted to engage the apertures 2 of the ears.

The lower ends of the rods 4 have mounted thereon washers locked by keys5, andwashers 5' are loosely mounted upon the rods directly under thefaces of the arms. Interposed between the washers 5 and the key lockedwashers at the ends of the rods, springs 6 are loosely mounted upon saidrods, whereby they exert a downward pull upon the same. This downwardpull of the rods is checked by keyed washers 5", which engage the uppersurfaces of the arms 3.

From the foregoing description it is apparent, when the latch mechanismis in the position shown in Figure 2 of the drawings, the cover isfirmly looked over the mouth of the can.

Should it be desired to remove the cover from its locked position, it isonly necessary to lift the pair of hooked rods to the position indicatedin dotted lines Figure 2.

Figure 6 illustrates a slight change of the position between the bracket3 and ear 2, whereby the rod 4 is arranged to lock the cover Btangentially, said arrangement being for the purpose of more readilyadjusting the clip member.

Thereafter, the hooked rods are swung outwardly, as indicated in dottedlines Figure 2, whereby the cover is entirely freed from the latchmechanism, and it can then readily be removed.

It follows in order to close the cover it is only necessary to insertthe same over the mouth of the can and swing the locking rods to theposition shown in Figure 2, whereby the nosed ends 4' of said rods aresocketed snugly within the apertures of the ears 2, whereby the springs6 will exert a downward pressure upon the cover to prevent itsinadvertent removal.

It should be noted that the apertured ears 2 project beyond theperiphery of the cover and hence when said cover is slipped over themouth of the can the projecting tongues serve as handles, whereby theyare utilized to rotate the cover in a position of alignment with thenose portion of the spring controlled rods, whereby said rods aremanipulated for locking engagement. In other words, the tongues servetwo purposes for convenience in operation of the device. 7

It should also be noted that in assembling the latch mechanism, it canbe done with a set of meta-1 screws without leaving any gpenings in thecover, which would otherwise result 'in p"er'-- ery thereof, the outerend of said ear having a keeper opening, a bracket rigidly's'ecilfedtothe sidewall of the an having a fadiallyprojectin'fg arm provided with aguide opening, Sal d a'lifm extending beyond 'theear, a latch rodslidably prim, mi s -n lly iib in rifle latch nose in a lowered earengaging position.
